Investors have abandoned Research In Motion, which may finally make it a good investment again. Twenty months ago, the smartphone company's shares traded at $85. The stock now changes hands at around $49. But there are good reasons to expect that it won't stay that low for long.

Research In Motion reported better than expected earnings Thursday, blunting fears that the Blackberry-maker is losing ground to smartphone rivals Apple and Google. But investors pushed shares down 3% in after-hours trading on secondary results that came up short of Wall Street's hopes.
